Fun fact: interior air in commercial airliners is not "recycled" by the air conditioning; rather, new air is constantly being pumped in from the outside via the engine's compressor, a convenient source of warm, high-pressure air used by the pressurization system and other things.
If the pressure gets higher than it's supposed to, a some is allowed to escape, so you get constantly refreshing air.
@brion But seriously, before my first trans-atlantic flight I didn't realize there is a generic smell of human bodies.
@deshipu heh yeah it's still a lot of people in a small space :D
i hope everyone showered before they boarded <3
@deshipu on a more positive note, the first time i realized that there's a *cat body smell* if you bury your head in their fur and just breathe in.... made me happy :D
but the cats actually clean themselves ;)
